Black normally follows with ...e6 and the break ...c5 to challenge the center. The solid Black setup with pawns on c6 and d5 against White's e4 pawn, often leading to a healthy pawn formation where Black can develop the light-squared bishop outside the chain. After ...c6 and ...d5, Black challenges White's central pawn without shutting the c8 [bishop](https://georgelichess.com/glossary/bishop.md) behind a pawn on e6. The most common versions are the Classical (Black takes on e4 and plays ...Bf5), the Advance (Black plays ...Bf5 against a pawn on e5), and the Exchange. The Classical version is very healthy: there are no [weak pawns](https://georgelichess.com/glossary/weak-pawn.md), Black has a free bishop, and White gets a small space edge at most. Black normally follows with ...e6 and the break ...c5 to challenge the center. The Advance version creates a chain with pawns on d4 and e5 against c6 and d5, where Black attacks the base with ...c5 and ...Qb6. The [endgames](https://georgelichess.com/glossary/endgame.md) are often pleasant for Black, because pawn weaknesses are rare and the bishop is not bad. The price is some passivity, so Black must reach a good setup before White gets [tactics](https://georgelichess.com/glossary/tactic.md). When playing against it, a [space advantage](https://georgelichess.com/glossary/space-advantage.md) and a kingside attack work well, but attacking before the pieces are developed is a [mistake](https://georgelichess.com/glossary/mistake.md). For Black, the common error is delaying the ...c5 break so long that the position gets cramped. Tip: develop the bishop before closing the chain with ...e6, otherwise the c8 bishop is shut in. ## Example position Black has pawns on c6 and e7 with the bishop on g6 outside the chain. Notice there are no weak Black pawns. Position (FEN): `r2qkbnr/pp1nppp1/2p3bp/8/3P3P/5NN1/PPP2PP1/R1BQKB1R w KQkq -` It sits close to [French structure](https://georgelichess.com/glossary/french-structure.md). The pawn chain where White has pawns on d4 and e5 against Black pawns on d5 and e6, giving White space on the kingside and Black a bad c8 bishop and counterplay against the d4 base. Also worth reading is [Semi-open defense](https://georgelichess.com/glossary/semi-open-defense.md). A semi-open defense is any Black reply to 1.e4 other than 1...e5, such as 1...c6, 1...e6, 1...d6 or 1...c5, in which Black meets White's central pawn from the side instead of facing it head-on.
